OPTImess laser sensors - due to their small size, high measurement frequency, and accuracy as well as their characteristic feature of being capable to operate in nearly all environmental conditions - are developing into a nearly universal measuring device in the areas of research & development, production, quality control and testing.

In geodesy, distance measurements by means of optical triangulation have been used for Ordnance Survey for a long time. On the basis of a known basic length and by defining two angles, it is hereby possible to determine exactly the position of a required point. The OPTImess sensors operate according to the same method.

The laser beam, which is projected by an optical installation, appears on the measuring object''s surface as a diffuse reflecting light spot. This spot is again projected by a second optical installation onto the detector. Each movement of the measuring object in the direction of the beam towards the receptor will result in a movement of the projected spot on the photo detector.

The OPTImess sensors have been developed for the exact measurement of measurable variables as, for example, positions, dimensions, vibrations and thicknesses in the industrial sector.
